Patent number: 8291559Abstract: A method of manufacturing a filter circuit including series and parallel coupled BAW resonators is given which compensates for frequency tolerances of the resonators which are due to the manufacturing process. The new method includes measuring a resonance frequency of at least one type of the BAW resonators produced on a wafer and defining a deviation from a desired frequency. A trimming layer is then deposited onto the entire wafer. At last, a thickness portion of the trimming layer is selectively removed, the portion being dependent on a location on the wafer and on the calculated deviation of the resonance frequency at this location.Type: GrantFiled: February 24, 2009Date of Patent: October 23, 2012Assignee: Epcos AGInventors: Habbo Heinze, Edgar Schmidhammer, Monika Schmiedgen

Patent number: 7961066Abstract: The invention relates to a filter operating with bulk acoustic waves, comprising at least one first resonator and at least one second resonator. In the at least one first and second resonator, a longitudinal acoustic mode is capable of propagation, for which normal dispersion is adjusted in the first resonator and abnormal dispersion in the second resonator by selection of the material and the relative layer thicknesses. In particular, the power compatibility of the filter at the higher frequency edge of its passband can be improved.Type: GrantFiled: December 4, 2006Date of Patent: June 14, 2011Assignee: EPCOS AGInventors: Habbo Heinze, Pasi Tikka, Edgar Schmidhammer

Patent number: 7636026Abstract: A bulk acoustic wave resonator includes an acoustically active area where an acoustic wave is excitable, and a transition area adjacent to an outside edge of the acoustically active area. A critical frequency of the acoustic wave in the transition area differs from a critical frequency of the acoustic wave in the active area. The transition area includes an additional layer. The bulk acoustic wave resonator includes electrodes for electrically connecting to electrical supply lines. The additional layer is irregular in areas adjacent to junction areas between the electrical supply lines and the resonator.Type: GrantFiled: July 30, 2007Date of Patent: December 22, 2009Assignee: EPCOS AGInventors: Habbo Heinze, Edgar Schmidhammer

Publication number: 20090079521Abstract: The invention relates to a bulk acoustic wave filter comprising at least one first resonator and at least one second resonator. A longitudinal acoustic mode for which normal dispersion is adjusted in the first resonator and abnormal dispersion is adjusted for the second resonator by selecting the material and the relative layer thicknesses, is able to propagate in the resonators, thus making it possible to improve especially the power compatibility of the filter at the higher frequency edge of the passband thereof.Type: ApplicationFiled: December 4, 2006Publication date: March 26, 2009Inventors: Habbo Heinze, Pasi Tikka, Edgar Schmidhammer

Publication number: 20080272853Abstract: A filter for use with bulk acoustic waves includes an input port and an output port. The input port and the output port are symmetrically operable. Signal paths extend from a terminal of the input port to a terminal of the output port. Bulk acoustic wave resonators are in the signal pats. The bulk acoustic wave resonators are arranged symmetrically in the signal paths. A complex impedance associated with each signal path is provided for electrically matching to a corresponding connection.Type: ApplicationFiled: June 3, 2005Publication date: November 6, 2008Inventors: Habbo Heinze, Edgar Schmidhammer, Pasi Tikka

Patent number: 7385467Abstract: Proposed is a resonator which works with bulk acoustic waves and is based on a layer structure known in the art, which is arranged over a substrate. According to the invention, the total surface of the layer structure, including all resonators contained therein, is covered with a dielectric layer and a metal layer which together form an acoustic mirror, a low-k dielectric being used for the dielectric layer. The total-surface mirror offers broadband functionality over a suitable frequency range. The dielectric contained within the mirror acts as a sealing protective layer for the resonator or resonators.Type: GrantFiled: June 23, 2003Date of Patent: June 10, 2008Assignee: EPCOS AGInventors: Ralph Stoemmer, Habbo Heinze

Patent number: 7187109Abstract: Overlapped electrodes of an electrical component are dimensioned in such a way that when there is translational displacement of one electrode in relation to the electrode situated opposite, their area of overlap remains within a manufacturing tolerance ?/2, and also remains constant within the tolerance limits when there is a simultaneous rotation of the electrodes with respect to one another. This is achieved in that the intersecting edge pairs of the overlapping electrodes are designed parallel to one another, whereby the length, measured in the direction parallel to the respective edge pair, of the corresponding electrode everywhere exceeds by ? the corresponding length of the area of overlap.Type: GrantFiled: July 28, 2004Date of Patent: March 6, 2007Assignee: Epcos AGInventors: Pasi Tikka, Ralph Stömmer, Edgar Schmidhammer, Habbo Heinze

Patent number: 6992400Abstract: A method for improving heat dissipation in an encapsulated electronic package usually referred to as a chip-size SAW package. The package comprises one or more acoustic-wave components fabricated on a die, which is disposed on an electrically non-conductive carrier separated by electrically conducting bumps. The top of the package is covered by a laminate and a hermetic seal layer. Heat dissipation can be improved by removing a part of the laminate and then depositing a layer of thermal conducting material on the package, and by providing one or more heat conducting paths through the carrier.Type: GrantFiled: January 30, 2004Date of Patent: January 31, 2006Assignees: Nokia Corporation, Epcos AGInventors: Pasi Tikka, Edgar Schmidhammer, Habbo Heinze, Reiner Welzer, Herbert Zidek, Ansgar Schäufele, Juha Ellä
